GRAIN THRASHER AND SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 259,264, dated June 6,1882.

Application filed November 12, 1880. (No model.)

To all whomc't may concern:

Be it known that I, CHRISTOPHER BLINN, of

16,1871, No. 114,974; of September 7, 1875, No. 167,570, and of June 20, 1876, 1 T0.179,064..v

The present invention belongs to that class of machines known as oscillators or vibrators, in which the straw-conveying table has a reciprocating or vibrating motion 5 and the novelty consists in certain novel improvements, which will be fully understood from the followin g description, when taken in connection with the annexed drawings.

In the'accompanying drawings, Figure 1 is a side elevation of my improved machine. Fig. 2 is a longitudinal vertical central section of the same. Fig. 3 is a perspective of the deflector. Fig. 4 is a perspective view of the beater. Fig. 5 is a perspective view of the combined rake and beater.

The same letters of reference indicate the same parts in all the figures.

The great desider'atum in all thrashing-machines and, separators is to arrest the straw, after it leaves the thrashing cylinder, as speedily as possible and to deliver it over to the grain-separatin g devices in order to prevent its being thrown through, or nearly through,

ration. This is the object of my invention, and I employ the following instrumentalities: The framework of the machine isof the usual or any suitable construction, and contains the usual fanning and screening devices.

A represents the cylinder; B, the concave; O, the grate, and D. the vibrating shakingtable, all of which parts may be constructed in the manner represented, or in any other suitable way. Just in the rear of the cylinder A is a beater, E, revolving in the direction indicated by the arrow upon its pulley, and composed of radial blades or wings at, extending from a shaft, F, upon the end of which, on the outside of the machine, is a driving-pulley, Gr, Fig. 1. The blades or wings a, instead of being radial, may run past the center of the shaft F, if desired. This beater, as before stated, is just in the rear of the thrashing-cylinder, and is as wide as the space between the sides of the machine. Its height above the shaker D is determined by the inclination of the grate or concave, and it should be so situated that the straw leaving the thrashing-cylinder would be thrown directly against it, and not under .it or above it.

In certain kinds or conditions of straw it may be found useful to employ the curved deflector H, which should be set directly over the beater E.

Just behind the beater E is a combined revolving rake and heater, I, substantially such as shown in L. G. Royers patents of September 7, 1875, and of June 20, 1876, before rc- I ferred to, though the only essentials of this device are that, in addition to its having wings or blades to beat out the grain, it should have also teeth to pull apart the bunches and aid in conveying the straw away from the beater E, and assist it in its passage through the machine. This rake and beater I is driven in the direction indicated by the arrow by a pulley, K, on the outside of the machine. The height above the shaker D of both the beater E and rake I is immaterial, so long as they are not so high above it that the straw would be thrown under them by the thrashing-cylinder.

As before stated, the essential function of the beater E is to catch the straw as it is thrown from the thrashing-cylinder and turn it down upon the shaker, by which the motion of the straw is arrested until the revolving rake catches it and pulls it away, thereby preventing the machine from choking up at this point.

Having thus fully described my invention, I

claim- 1. In a thrashing and separating machine, the combination of a revolving cylinder, a concave, a grate, a revolving beater arranged suf ficiently near the cylinder to deflect thestraw downward, a revolving rake, and a vibrating rectly in the rear of said cylinder, a deflector shaker and carrier, all constructed and arranged to operate substantially as set forth.

2. In a thrashing and separating machine,

directly over said heater, a combined rake and beater directly in the rear of said deflector, and a vibrating shaker under said beater, de-

the'combination of a thrashing-cylinder, a flector, and rake, substantially as and for the grate, a rotary beater, a deflector, a rotary purpose specified.

beater which also acts as a rake, and a shaker, substantially in the manner and for the purposes described.

3. In a thrashing-machine and separator, the combination of the followinginstrumentalities: a thrashing-cylinder, a revolving beater di- In testimony whereof I have hereunto set my hand.
